Mrbb,
The OP already stated what rifle he bought (it's a cz527 ) and it should be plenty accurate. If he was asking for advice BEFORE buying a rifle I'm sure we all would have suggested an 06, a.270, .30-30, etc. But he already bought the rifle.
The OP also began this post to ask what ammo would be best.
Your two primary concerns of innaccurate rifles(milsurp) and poor ammo selection were taken care of in the first post.
I could hunt whitetail the rest of my life with a 527 in either of those options and I would continue to kill deer every year.
There is always a "better" alternative available. But it's not necessary.
Know your equipment, know it's capabilities and it's limitations, then go kill deer.
